Claude Code Adds Cross-Session Messaging on macOS
Anthropic has updated Claude Code so that separate coding sessions can message each other directly, removing the need to manually copy context between Terminal windows. The company shipped the feature in Claude Code version 2.1.224, released on Friday for macOS and Linux. Two new tools power it: ListAgents, which finds other active sessions running on the Mac, and SendMessage, which delivers the message. A session that receives one shows it as a labeled card with a link back to the sender.
